General Guidelines

Some Basics
1. Under Board "Frequently Asked Questions" (FAQs) there are 3 sections dealing with General Forum Usage, User Profile Features, and Reading and Posting Messages. These deal with everything from Avatars to Your Notifications. Most general technical questions are covered there. Here is a link to the FAQs. https://forum.chesstalk.com/help
2. Consider using the SEARCH button if you are looking for information. You may find your question has already been answered in a previous thread.
3. If you've looked for an answer to a question, and not found one, then you should consider asking your question in a new thread. For example, there have already been questions and discussion regarding: how to do chess diagrams (FENs); crosstables that line up properly; and the numerous little “glitches” that every new site will have.
4. Read pinned or sticky threads, like this one, if they look important. This applies especially to newcomers.
5. Read the thread you're posting in before you post. There are a variety of ways to look at a thread. These are covered under “Display Modes”.
6. Thread titles: please provide some details in your thread title. This is useful for a number of reasons. It helps ChessTalk members to quickly skim the threads. It prevents duplication of threads. And so on.
7. Unnecessary thread proliferation (e.g., deliberately creating a new thread that duplicates existing discussion) is discouraged. Look to see if a thread on your topic may have already been started and, if so, consider adding your contribution to the pre-existing thread. However, starting new threads to explore side-issues that are not relevant to the original subject is strongly encouraged. A single thread on the Canadian Open, with hundreds of posts on multiple sub-topics, is no better than a dozen threads on the Open covering only a few topics. Use your good judgment when starting a new thread.
8. If and/or when sub-forums are created, please make sure to create threads in the proper place.
Debate
9. Give an opinion and back it up with a reason. Throwaway comments such as "Game X pwnz because my friend and I think so!" could be considered pointless at best, and inflammatory at worst.
10. Try to give your own opinions, not simply those copied and pasted from reviews or opinions of your friends.
Unacceptable behavior and warnings
11. In registering here at ChessTalk please note that the same or similar rules apply here as applied at the previous Boardhost message board. In particular, the following content is not permitted to appear in any messages:
* Racism
* Hatred
* Harassment
* Adult content
* Obscene material
* Nudity or pornography
* Material that infringes intellectual property or other proprietary rights of any party
* Material the posting of which is tortious or violates a contractual or fiduciary obligation you or we owe to another party
* Piracy, hacking, viruses, worms, or warez
* Spam
* Any illegal content
* unapproved Commercial banner advertisements or revenue-generating links
* Any link to or any images from a site containing any material outlined in these restrictions
* Any material deemed offensive or inappropriate by the Board staff
12. Users are welcome to challenge other points of view and opinions, but should do so respectfully. Personal attacks on others will not be tolerated. Posts and threads with unacceptable content can be closed or deleted altogether. Furthermore, a range of sanctions are possible - from a simple warning to a temporary or even a permanent banning from ChessTalk.
Helping to Moderate
13. 'Report' links (an exclamation mark inside a triangle) can be found in many places throughout the board. These links allow users to alert the board staff to anything which is offensive, objectionable or illegal. Please consider using this feature if the need arises.
Advice for free
14. You should exercise the same caution with Private Messages as you would with any public posting.
15. Have fun!

Mystery game #67: White promotes two pawns, but loses the game!!

Here is the text of an interesting game. You can discuss the game, player strengths, variations, era, setting, time control, etc. I will provide all, data in a few days. Enjoy!!
Another apology for my minor carelessness in entering this game. I wrote an analysis variation near the end, instead of the actual game. We are OK to move 37. I have too many pieces of paper on my desk at the moment!
Geoff McKay (2159) -- Frank Dixon (2069), Kingston 1999, Kingston Chess Club, G/30' (2), played 1999-05-31. TD: Frank Dixon. Sicilian, Scheveningen / Keres, B81.
This was the last event of the 1998-99 KCC season, before the summer break; it was a fun G/30' format. Geoff had just won the KCC Championship with 7/8 and a 2305 performance rating; I was second, with 5.5 and 2221, and our head-to-head game from that event was the decisive one, as Geoff won in excellent style.
The razor-sharp Keres Attack with 6.g4 against the Scheveningen Sicilian has become steadily more popular in recent decades. The namesake stem game was Paul Keres 1-0 Efim Bogolyubov, Salzburg 1943, where White won in dashing fashion. However, IM Vassily Panov had played the line before that in some Soviet games. IM Al Horowitz's 1964 volume 'Practical Chess Openings' uses only a footnote to cover the line, but with the establishment of the Chess Informant system by a group of Yugoslav geniuses in the mid-1960s, the line was assigned its own ECO code, B81, one of 500 in a tightly formatted and wonderfully designed structure, covering all opening variations.
We follow O. Jacobsen -- R. Huebner, Denmark vs. West Germany, Berleburg 1971, until White's 11th move. That game saw 11.f4 Nc4 12.Qe2 Nxe3 13.Qxe3, and was drawn in 39 moves, with Black also castling queenside. See 365chess.com. With 11.Qe2, Geoff prevents the knight advance into c4, also preserving his dark bishop; this may be a new move.
After Black's 12th, he has played five knight moves, has only also developed his queen, with his King still in the centre, so Black's development lag is a concern.
Geoff then plays a fantastic concept, with a piece sacrificed, and a wild sequence with his 14th through 16th moves!! This was an idea that someone like GM Mikhail Tal would approve! For his piece, White gets very dangerous attacking chances. Pondering my position after 17.f4, I thought I may already be lost, but resolved to evacuate my King to the queenside, and aim for counter-attack there; I do have some potential. White's pawns become truly menacing after 23.g6; Black's game hangs by a thread, I think.
But I manage to create some threats with my bishop, activity down the b-file, and a strong queen move 29...Qa5!, threatening mate.
White queens his g-pawn, and uses the new queen to cut down Black's attacking force, winning a rook for it. He then has to defend the threatened mate on a3 after 31...Ne3!, which cut the Q/g3's defence of a3. Another very tempting move was 31...Nxa3, but I think this loses for Black, as the g1-a7 diagonal is open to White's attack on Black's K/a7, combined with too much power down the g-file.
I believe my move 36...Nxd3 is an error, which is not apparent until White's error on move 40. I needed to force a draw by perpetual check with 36...Nc2+! By this stage, both players were very short of time, but I had a couple minutes left, while Geoff was down to half a minute or so.
Black's mating sequence works well to win the game, with his pieces cooperating optimally; this even after White queens his second pawn with 39.h8Q.
BUT, if White had played 40.Ka2!! instead of 40.Kb1?, then he could have won through a sparkling idea: 40.Ka2!! Bd4 (aiming to set up a windmill tactic with 41...Rb2+ next) 41.Qxd4+!! exd4 42.Qxd4+!, and now Black's King is suffering. Should all remaining majors be exchanged, which Black can hardly avoid, then White wins by one move by marching his h2-pawn to queen!!
Overall, an exciting and memorable battle, which did give Black a bit of payback for losing the decisive tournament game to Geoff!!
I am going to consolidate the correct game score for this game into one post, to eliminate any confusion.
Geoff McKay (2159) -- Frank Dixon (2069), Kingston 1999, Kingston Chess Club spring rapid (2), played 1999-05-31, time controls G/30', TD Frank Dixon, Sicilian, Scheveningen, Keres, B81.
